How high can the Zener current go?


The permissible value of the Zener current varies according to the Zener voltage, the current application conditions (usage conditions), and the mounting conditions.
Concretely, calculate the junction temperature for the actual usage conditions and verify that the absolute maximum rating for the junction temperature (Tj) is not exceeded.
For the concept and junction temperature calculation method, refer to the following document provided on this website.
